Course Description

An in-depth course that focuses on two key areas, Linux high availability (HA) clustering and HA storage administration. Storage is integral to many HA clusters so as to make use of clustered storage technologies to enable active/active configurations.
Over the course of many in-depth lab exercises, each student will assemble a realistic three-node Linux cluster utilizing best practices. Each node has three network interfaces and each student's cluster has its own dedicated cluster VLAN.
The class contains a storage array for shared LUNs among the nodes. This enables students to perform very real world tasks in a real world setting, including multipathing, redundant ring communication, last man standing cluster, and shared storage scenarios. Course topics include: Cluster Architecture & Design, Pacemaker, Corosync, Fencing, Resource Management, Advanced Resource Management, Multipathing, Cluster LVM, Global File System v2.
The unprecedented real-world nature of this class requires a classroom configuration that would be daunting (but not impossible) to put together in a physical or virtual classroom. The Guru Labs online classroom solution, RLabs, instantly and easily deploys a classroom with the exact configuration needed to support this class. Students will be able to focus on the course topics rather than configuration settings outside the scope of the course.

Course Length: 4 Days
Course Tuition: $2590 (US)

Prerequisites

This course requires an advanced knowledge of Linux system administration. These skills are taught in the "Enterprise Linux Systems Administration" and "Linux Fundamentals".

Linux Unix Uses & Stats

Linux supports many efficient tools and operates them seamlessly. Because it's architecture is lightweight it runs faster than both Windows 8.1 and 10.

Security:

Because Linux is an open-source software, anyone can contribute code to help enhance the users’ experience i.e., adding features, fixing bugs, reducing security risks, and more.

Software Development:

The terminal in Linux is a *wild card*. You can do almost anything with it. This includes software installation, application and server configurations, file system management, and etc.

Large-scale:

Open-source projects benefit from having an attentive community. As a result, Linux is more secure than Windows. Instead of installing anti viruses to clean malware, you just have to stick to the recommended repositories.

Efficient:

Developers have the convenience of running servers, training machine learning models, accessing remote machines, and compiling and running scripts from the same terminal window.

Free:

Linux is free (you can put it on as many systems as you like) and you can change it to suit your needs.

Cons

Learning Curve:

Linux is not for everyone, there is a learning curve in switching to Ubuntu. To actually learn Linux efficiently would take a user one to several years.

No Tech Support:

Unlike Windows, there isn’t a dedicated tech support, so getting help for things is up to you.

Designer Compatabilty:

Linux is not as user friendly as Windows or as ‘straight out of the box design’ As an example for design choices, Adobe hasn’t released any of its products to Linux users. So it’s impossible to run them directly. The Ubuntu alternative is a free software called GIMP.

Gaming Capabilities:

Most games aren’t available in Linux. But that’s not to say you can’t make it happen, it's just not as easy.
